摘要： An angular velocity sensor 1 includes support members 10A1, 10A2, 10B1 and 10B2, bonded to two nodal points of a pillar-shaped oscillator, generated on oscillations of the oscillator, in a manner of sandwiching the nodal points from upper and lower sides of the oscillator. The support members simultaneously serve for mechanically supporting and providing for electrical connection of the oscillator. Upper support members 10A1, 10A2 and lower support members 10B1 and 10B2 for the nodal points include bent parts, the bent parts being bent in the same direction with respect to the longitudinal direction of the oscillator. The upper support members and lower support members also include arms 11 extending at right angles to the up-and-down direction and to the longitudinal direction of the oscillator and connecting portion 13 for the arms and the oscillator.
